CacheCard is a NIC-based cache for static and dynamic web content in a way that allows for implementation on simple devices like NICs. It requires neither understanding of the way dynamic data is generated, nor execution of scripts on the cache. By monitoring file system activity and potential non-determinism incurred by scripts, the authors determine all data sources for specific requests. For instance, if a deterministic script opens a set of files or a database tables, these files and tables, as well as the script itself will be in the set of data sources for this URL. Caching the dynamic data is possible, since they can invalidate cache entries when any of the sources changes.
